+
+This chapter is dedicated to the most important definition principle after
+recursive functions and datatypes: inductively defined sets.
+
+We start with a simple example \ldots . A slightly more complicated example, the
+reflexive transitive closure, is the subject of {\S}\ref{sec:rtc}. In particular,
+some standard induction heuristics are discussed. To demonstrate the
+versatility of inductive definitions, {\S}\ref{sec:CFG} presents a case study
+from the realm of context-free grammars. The chapter closes with a discussion
+of advanced forms of inductive definitions.
